The native frame adjustments to handle the DR handler being on the native stack previously failed to handle an application with a sigaltstack. We correct that here. Adds sigaltstack testing to the api.detach_signal test. With a smaller stack, this exercises the stack-too-small error message path from DR. Issue: #1921
